The Nintendo president was equally down on the recent enthusiasm over 3D technology, saying "I have doubts whether people will be wearing glasses to play games at home. How is that going to look to other people?". Iwata also said Nintendo would need to look into the "possible health effects" of playing games in 3D for prolonged periods of time.

I don't know. How does shouting/blowing into a handheld on the train make you look?
